e WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 752,767, dated February 23, 1904.

Application led December 6, 1901. Serial No. 84,873. (No model.) Y

To @ZZ whom it may concern.-

Be it known that I, J AMES H. FootrE, acitizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Weather- Strips, of which the following is a specification.

The object of my invention is a weatherstrip which may be attached to a windowsash, window-frame, door, or door-frame without marring them and which forms an eiiicient means -for preventing the entrance of cold air, rain, dust, &c., andv for overcoming rattling.

I have illustrated my invention as applied to window-sashes in the accompanying drawings, in which p Figure 1 is a rear elevation of a window frame and sash, showing the sash provided with a weather-strip embodying my invention. Fig. 2 is a central vertical sectional view of the same, taken upon line .e e of Fig.

1. Fig. 3 is a horizontal sectional view upon an enlarged scale, taken upon line w Fig. 1. Fig. 4 is a detail perspective view of the strip used upon the meeting-rail of a windowsash. Fig. 5 is a detail vertical sectional view, upon an enlarged scale, of a slightly-modified form of strip for the meeting-rails. Fig. 6 is an enlarged detail vertical sectional View of the strip secured to the lower rail of the bottom sash.

Referring to the drawings, a strip A, of resilient metal, is bent inward along a line parallel to its edges, forming a narrow flange a and a broad liange a', which stand at an angle to each other. In the preferred form flange a is again doubled upon itself.

In applying strip A to a window straight vertical grooves 6 6 are formed upon the outer surfaces of the side rails 62 63 of the upper and lower sashes B and B,a horizontal groove 64 is formed in the meeting-rail 65 of the lower sash, and longitudinal grooves 66 and 67 are cut upward into the lower rail 6s of the lower sash. Into grooves 6, 6', 6*, and 66 iianges a of strips A are then inserted and may be held therein by any suitable means. In the predoubled upon itself spread apart after being inserted within the groove, and thereby hold itself in place. In the side rails of the upper sash the outer free end or iiange a' bears outward against the outer member c of the window-frame C and in the lower sash iiange a bears outward against parting-strip c of the frame.

Flange a of strip A, secured to the meeting-rail 65 of the lower sash, bears outward Vagainst meeting-rail 6 of the upper sash. I prefer to carry iiange a down below and bend it back beneath the edge of the meeting-rail 65 in a flange a2, which has a series of slots a3 to engage pins 6lo in said rail to prevent iiange a from being bent outward by careless use, so that it catches against the upper face of meetingrail 6,- but for ordinary purposes flange a need only be turned in slightly at its outer edge, as shown in Fig. 5.

In the lower rail 68 iiange a bears against sill c2 of the window-frame and hasv a flange a2 similar to the preferred form used upon the meeting-rail, except that it is not slotted. Flange a? projects into groove 67. This form is one which may be easily applied to a door, in which case grooves 6 67 would be formed in the edges of the door and flange a' would bear against the door-frame.

Inluse the angle between flanges a and a', strip A being resilient, tends to maintain itself in its primitive degree, and this tendency al ways keeps flange' a in firm contact with the surface opposite it, but does not press with a force such as to render the movement of the window or door stiff, while at the same time it forms an effective barrier to the entrance of dust, wind, &c. It is readily seen that a window or door of the forms in common use need not be changed in order to be fitted with my weather-strip, so that the efficiency of the window or'door itself in excluding dust and the wind and rain is not lessened nor its strength impaired by the cutting away any of its bearing-surface'. The strip is, moreover, readily applied to old buildings, the only step necessary in tting them in place being to form the aforementioned straight grooves,

i ferred for-m flange a will by reason of being which, as an examination will show, always` come at parts of the window or door which are readily accessible.-

It is obvious that in place of fitting strip A in the sash and door it might be `placed in the frames, which would be grooved to receive Iiange a, and flange a' would then bear against the sash or door.

What I claim is- 1. A window or door the sash orA door of which has straight grooves formed therein near its edge, in combination with a strip of metal bent inward forming flanges which stand at an angle to each other one ange being bent again and inserted into one of the grooves in which 4it holds itself the other or free end JAMES H.
